TENSION DEVICE ron anur nnssiuq MAC INES;

To all whom itrmay concern.

Be it known'that I, OCTAVE CHARBQN- NEAU, a citizen of the United'States, residing at Providence, in the county of Providence and State of Rhode Island, have inventeda new and usefullmprovement in Tension Devices for Yarn-Dressing Machines, of which the following is a specie fication.

This invention relates to certain new and useful improvements in yarn dressing machines.- c

' The primary object of the invention is to provide means for indicating to the operator any variations in the draft or pull on the yarn effected by varying atmospheric conditions, so that the operator may adjust the draft means toeffect proper draft on the yarn upon change in the atmospheric conditions. I

In order to effect proper laying-of the thread upon the reel it is necessary that a predetermined draft or tension'be placed upon the yarn so that such tension or draft is uniform regardless of atmospheric con- For instance in dry weather, or under interior dry atmospheric conditions, the machine is set accordingly, and should the atmosphere change to a considerable degree of dampness, the yarn would expand or stretch, and as the reel retains its relative position, the take-up in yards to form the piece would be altered accordingly, and.

uniformity destroyed.

The present invention, therefore in brief, 7

proposes means for enabling the operator to ascertain when the tension on the yarn varies, so that h may adjust his take-up or reel accordingly, in order to compensate for such change in atmosphere whether the change be one of climatic conditions or variations in the atmosphere in the room in which the dressing machine operates.

In the drawings-Figure 1 is a perspective view of a dressing machine having the present invention incorporated therein. Fig. 2 is an enlarged detail view, in fragment, of one of the two devices that support the tension roll. Fig. 3 is a front side elevation of Fig. 2, parts being omitted. Fig. 4 is a detail view in front elevation of the indicating means, partly in section. Fig. 5 is a fragmentary sectional detail view of one of v Specification of Letters Patent.

the mountings of the tension roll. Fig. 6 is a plan view of the adjustable bracket, and Fig. '7 is a similar view of one of the tension roll carriers. i v i In proceeding in' accordance with the pres ent invention a yarn dressing machine is employed which comprises the tension roll 1, 'a sizing pan P and steam coils C, the yarn guide roll G'through the reed G to the reel (not shown). The pull on the yarn is regulated ,bya series of drive rolls so as to give avarying draft or pull on the yarn. All'of the aforementioned features are old. v

The present invention resides particularly in an indicating mechanism associated with the tension roll 1, which 'roll is supported on its shaft 1 in'a carrier 2, the carrier having two gears 33 located at its top and bottomwhich gears mesh with the teeth of a double rack 4: that is appropriately secured to vertical parts or standards F of the machine frame. The carrier 2 is formed with a hook 5 as shown more particularly in Fig. 7 which hook has secured thereto one end of a chain 8, the chain 8 engaging over, around, and under a gear 9 which gear is supported upon an adjustable bracket 10 that has a slot 11 in which latter is received a rectangular stud 12. The gear 9 has a se ries of numerals 1 1 on its face as shown in Fig. 4: which coiperate with a pointer 13 rigidly secured to the movable journal 15 of the gear 9. The chain passes over and down one side of an idler gear 16 and has a weight 17,0 11 its lower end. In dry weather or under an interior dry atmospheric condition the machine being set accordingly a certain degree of compactness follows the taking up of the yarn by the reel. Should a change in dry atmosphere to one of considerable dampness be experienced, the yarn would expand or stretch and as the reel retains its fixed position, there would result variation in the take-up in yards to form the piece. In accordance with the present invention the above stated change in at- 13 will point to a difierent number on'the gear 9. The operator will thus know that the take-up or reel must be instantly adj usted so as to restore the tension to normal, which latter is indicated by the numeral of the gear 9 which the pointer 13 was originally set to point to.

It will thus be seen from the foregoing that by mounting the roll 1 so that same is tensioned uniformly and by actuating an in dicating mechanism by virtue of. any movement which the roll 1 may be permitted to have, due to stretching of the yarn under the action of moist atmosphere,- the movement of the roll permitted by said stretch will cause the indicator to be actuated to instantly enable the operator to ascertain the fact that the yarn has responded to a change in atmosphere and that resetting or readjustment of the tension roll to compensate for the change in atmosphere is necessary.

It will be understood that there is a carrier 2 with associated parts located at each end of the tension roll 1, so as to mount each end of the latter in the same manner.

Having thus described my invention, what Copies of this patent may be obtained for I claim as new and desire to secure by Letters Patent p v 1. In a yarn dressing machine, a double rack, a tension roll, a carrier therefor, said carrier having upper and lower gears meshed with the teeth of the rack, a rotatable gear having numbers on its face, a stationary pointer associated with the numbers, a gear below the last named gear, and a weighted chain connected to the carrier and engaged over the third named gear and thereunder and over the last named gear.

2. In a yarn dressing machine, a track, a tension roll carrier movably related to the track, an indicator including a rotatable element mounted independent of the carrier, and combined means to tension the roll carrier and to operate the rotatable element of the indicator including a flexible member connected to the carrier and passing over said rotatable element and having a weight connected thereto whereby to tension the flexible element and thereby the carrier so that each movement of the carrier will effect corresponding movement of the rotatable element.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

OCTAVE CHARBONNEAU.
